Circumstances:
Shortly after takeoff from Almaty Airport, while climbing to a height of 80 meters at a speed of 180 km/h, the left engine failed and caught fire. The captain decided to divert to the nearest Pervomaiski Airbase located 4,5 km from his position. On final approach, the aircraft stalled, hit a first building, several trees, two telegraph poles and eventually crashed on a second building. A stewardess was killed while 18 other occupants were injured, some of them seriously. The aircraft was destroyed.
Probable cause:
The left engine failed and caught fire shortly after takeoff due to the failure of the tenth cylinder, apparently due to poor maintenance on part of the company mechanics. Nevertheless, the techniques adopted by the pilot on short final were inappropriate, which contributed to the stall.
